The pan has lost its non-stick coating.

Restoring a Pan Without Non-Stick Coating

1. Season the Pan:

   • What You Need:
     • Vegetable oil (or another cooking oil with a high smoke point)
     • Paper towel or soft cloth
   • Steps:
     1. Clean the pan thoroughly with soap and water, removing any leftover debris or food particles.
     2. Dry the pan completely.
     3. Apply a thin layer of oil to the inside surface of the pan using a paper towel.
     4. Heat the pan on medium heat for 5–10 minutes until the oil begins to smoke slightly.
     5. Let it cool, then wipe off any excess oil.
     6. Repeat this process 2–3 times to build up a natural non-stick layer.

2. Use a Parchment Paper or Silicon Mat:

   • For tasks like frying or baking, lining the pan with parchment paper or using a silicone mat can prevent sticking without relying on the coating.

3. Add a Natural Non-Stick Layer with Salt:

   • What You Need:
     • Coarse salt
     • Paper towel
   • Steps:
     1. Heat the pan on medium heat.
     2. Add a thin layer of coarse salt and let it heat for a few minutes.
     3. Use a paper towel to rub the salt around the surface (wear gloves to avoid burns).
     4. Discard the salt and rinse the pan—this technique smooths out minor scratches and improves stick resistance.

4. Alternative: Use a Cooking Spray or Extra Oil:

   • Add a little more oil or a cooking spray before cooking to minimize sticking.

Safety Considerations

• Check for Damage:
  • If the pan shows signs of deep scratches or exposed metal, especially if it’s made from aluminum, it might be safer to replace it due to potential health risks from leaching.
• Avoid High Heat:
  • Without a non-stick coating, pans can get hotter faster, which may lead to food burning or sticking.
• Do Not Overuse Damaged Pans:
  • Prolonged use of severely scratched pans may lead to ingestion of small particles, which is undesirable.

When to Replace the Pan

• If the non-stick coating is completely gone or flakes are coming off regularly, it might be time to invest in a new, high-quality pan.
• Consider alternatives like stainless steel or cast iron, which are durable and naturally non-stick when maintained properly.
